Evaluation of the prevention effect of high-quality nursing quality control in disinfection supply center on nosocomial infection

To explore the application effect of high-quality nursing quality control in disinfection supply center. The control group consisted of 1850 medical devices managed using the conventional quality control mode from January 2021 to December 2021, while the observation group consisted of 1900 medical devices managed using the high-quality nursing quality control mode from January 2022 to December 2022. The qualified rates of equipment cleaning, sterilization, and packaging were analyzed in both the observation and control groups. The occurrence of nosocomial infections in 2021 and 2022 were compared, and the changes in the Beck-Srivaatava stress scale index (BSSI) and Symptom Checklist-90 scores of the staff before and after implementing the high-quality nursing quality control mode were analyzed. The qualified rate of equipment cleaning, sterilization, and packaging in the observation group were 99.08%, 99.73%, and 99.78%, respectively, which were significantly higher than those in the control group (P < .05). The incidence of nosocomial infections in interventional and surgical cases in 2022 was 0.79%, which was significantly lower than that in 2021 (P < .05). The BSSI score of female staff was (68.76 ± 7.81) points, which was higher than that of male staff (P < .05). After the implementation of the high-quality nursing quality control mode, the BSSI score of the staff was (47.76 ± 9.12) points, which was significantly lower than that before implementation (P < .05). After the implementation of the high-quality nursing quality control mode, the staff’s Symptom Checklist-90 scores for somatization, compulsion, interpersonal sensitivity, depression, hostility, and paranoia were (1.28 ± 0.29), (1.53 ± 0.24), (1.50 ± 0.21), (1.46 ± 0.32), (1.44 ± 0.26), and (1.38 ± 0.30) points, respectively, showing a decrease compared to before implementation (P < .05). The high-quality nursing quality control mode has great application value in the disinfection supply center. It can effectively improve the qualified rates of equipment cleaning, sterilization, and packaging, prevent nosocomial infections and improve the working pressure and psychological health of staff.


Introduction
[3] In addition, the disinfection supply center is also the main department for handling contaminated medical materials, so improving the management quality of the disinfection supply center is of great significance for ensuring the safety and reliability of medical supplies.High-quality nursing quality control refers to placing more emphasis on the responsibilities of nursing staff on the basis of routine nursing, ensuring that nursing services are more professional and of higher quality.[6] Based on this, the aim of this study was to explore the application effect of high-quality nursing quality control in the disinfection supply center.The results are reported below.

General data
This study was approved by the Ethics Committee of Renhe Hospital affiliated to China 3 Gorges University.The control Negative life events occurred in the past year; Patients with a history of mental illness.

Intervention methods
The control group was managed using a routine quality control mode: disinfection work was carried out according to the hospital's work system and procedures.The observation group was managed using a high-quality nursing quality control mode: An excellent nursing quality control team was established.The team held meetings to discuss and develop a detailed work plan, and conducted regular training and learning activities to impart the latest knowledge and skills in equipment management, disinfection, and infection control to nursing staff.The team also organized nursing staff to participate in lectures and discussions, inviting experts, scholars, or senior figures in the industry to provide professional explanations and exchanges on equipment management, infection prevention, and other aspects.After the meetings, team members provided detailed explanations and training to nursing staff on the principles and methods of disinfection and sterilization.They also strengthened guidance and supervision during practical operations, and organized inspections and evaluations of the effectiveness of disinfection and sterilization to ensure the quality and safety of disinfection and sterilization work; Through conducting research, an understanding of the actual situation in the hospital and center was gained, the problems and shortcomings of the existing system were analyzed, and based on the research results and actual situation, a new set of rules and regulations was formulated.These rules and regulations clearly defined the responsibilities, work processes, and operational standards of the disinfection supply center, ensuring that the staff had a clinical basis during the operation process.After the new set of rules and regulations was formulated, relevant experts and leaders were invited to review and modify them, ensuring the rationality and operability of the regulations.After the new set of rules and regulations were established, relevant training and publicity was provided to the staff; Performance assessment indicators and reward standards were set up based on work performance, work quality and work attitude.Excellent employees with outstanding performance were rewarded accordingly.Regular performance assessments were conducted, and based on the results, corresponding rewards and punishments were given.The assessment covered multiple aspects, including work quality, work efficiency, work attitude, and team cooperation.A punishment system was established to punish behaviors such as noncompliance with rules and regulations, work errors, and other forms of misconduct.Punishment methods could include verbal warnings, written warnings, fines, salary reductions, demotions, etc, based on the circumstances, with appropriate punishments given; Complete records and monitoring were conducted for all instrument cleaning procedures carried out in clinical areas to trace the entire process of each instrument from cleaning to use, including cleaning, disinfection, drying, packaging, storage, and other links.This ensured that each step adhered to the requirements of the rules and regulations, and improvements were made to address any issues that arose during actual work.A traceability mechanism was established to investigate instruments involved in past infection events, identify the source of infection, investigate the causes, and take timely measures to prevent similar incidents from reoccurring.Regular environmental cleaning was carried out, and standardized management of cleaning and disinfection procedures implemented in the department to ensure that all cleaning and disinfection work complied with the requirements of the rules and regulations; A professional psychological questionnaire was used to conduct a comprehensive psychological evaluation of the nurses in the disinfection supply center, including their emotional state, stress levels, and mental health.Regular counseling sessions were conducted for the nurses by psychological experts to monitor their life habits, economic conditions, cultural level, and acceptance level.The nurses psychological reactions and needs were taken into consideration, and timely psychological guidance and assistance were provided to them.

Assessment methods
The Beck-Srivaatava stress scale index (BSSI) [7] was used to assess the stress levels of the staff, with a total score of 138 points where a higher score indicates higher stress levels.Scores below 35 indicate mild stress, scores between 36 to 70 indicate moderate stress, and scores between 71 to 138 indicate severe stress; The symptom checklist-90 (SCL-90) [8] was used to evaluate the mental health of the staff, which includes 9 symptom factors, such as somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism.Each factor is rated on a scale from 1 to 5, with a higher score indicating a poorer mental health condition.The measurement data were expressed as (X± s), and the difference between groups was analyzed by t test.The count data were expressed as n (%), and the difference between groups was analyzed by χ 2 test.

. Discussion
The disinfection supply center is an important part of medical institutions.[11] Nosocomial infections are an important factor affecting the quality of medical care, and their harmfulness and scope of influence cannot be underestimated.The importance of nosocomial infection prevention in hospitals is increasingly being recognized.Therefore, staff need to strictly follow the procedures when organizing and disinfecting medical supplies to ensure the safety and reliability of medical supplies.[14][15] The implementation of high-quality nursing quality control aims to improve the quality of service to provide strong support for hospital infection prevention by standardizing operational procedures, strengthening training and learning, establishing service evaluation mechanisms, among other measures.This approach enhances the qualifications of nursing staff, cultivates their professional skills, improves their service awareness and service quality, and ultimately improves the supply and management of medical equipment and disinfectants.In addition, high-quality nursing quality control places more emphasis on the work environment and mental health of nurses, providing necessary support and resources to help them effectively cope with work-related stress and emotional distress.18] The results of this study show that the observation group's rates of qualified instrument cleaning, sterilization, and packaging were significantly higher than those of the control group (P < .05).This suggests that high-quality nursing quality control has a significant impact on the quality of instrument cleaning, sterilization, and packaging.The improvement in quality can be attributed to the observation group's detailed work plans, group discussions, and training programs that  ensure that all nursing staff are up-to-date with the latest knowledge and skills in instrument management, disinfection, and infection control.The regular training and learning activities can further enhance the professional level of nursing staff, strengthen their theoretical foundation and operational skills in disinfection and sterilization work. [19,20][23] Postconference lectures and training can ensure that nursing staff master the correct operating procedures.In addition, spotchecks and evaluations can help detect problems promptly and corrective actions can be taken.Moreover, setting performance evaluation indicators and reward criteria can motivate staff to work harder and be more focused.Providing corresponding rewards and recognition to outstanding employees can encourage them to continuously improve their work level and enhance their motivation and sense of responsibility towards work.26] The results of this study also showed that the incidence of hospital-acquired infections in 2022 was significantly lower than that in 2021 (P < .05).This suggests that high-quality nursing quality can effectively reduce the incidence of hospitalacquired infections.The reason for this improvement is likely due to conducting surveys to understand the actual situation of the hospital and disinfection supply center, which can help identify the direction and focus of improvements.This ensures that staff have clinical basis and guidelines during the operational process, thereby reducing the arbitrariness and uncertainty of operations.The establishment of a complete quality management system through recording and monitoring can improve the traceability and controllability of instrument cleaning work.Tracing the instruments that caused infection events, and identifying the source of infection can increase staff's awareness of the importance of instrument cleaning work, promoting implementation of responsibilities and problemsolving.29][30] This study used the BSSI scale to assess the stress levels of staff, providing a basis for corresponding intervention measures.The results showed that women staff had higher BSSI scores than men, indicating that women are more susceptible to stress in the workplace.Therefore, psychological interventions should be inclined towards women.This study also showed that after implementation of the nursing quality control model, staff BSSI scores and SCL-90 scores for some items were significantly lower than before implementation (P < .05).This is because the observation group organized personalized counseling and guidance from psychological experts for the nurses based on the evaluation results and the individual situation.This helps nurses recognize and cope with their psychological distress and stressors, and provides relevant psychological support and coping strategies to promote psychological health and emotional adjustment.By asking about nurses' living habits, economic conditions, educational background, and acceptance level, etc, more comprehensive understanding of their living and working environment can be obtained.3][34][35]

Conclusion
High-quality nursing quality control has great application value in the disinfection supply center, which can effectively improve the pass rate of instrument cleaning, sterilization, and packaging, prevent hospital-acquired infections, and improve staff's work pressure and psychological health.
